It's really awesome, better than GTA IV. From what i see in the official gameplay video i see: the shooting mechanics is from Max Payne 3, the car physics feel almost like a racing game and stick to the ground a bit better, the animals and wilderness from Red Dead Redemption, character switching, some vehicles from GTA IV returns to GTA V, car customization, weapon customization, more clothes, sports to play, heist missions, can dive underwater, and more.

Hope it will be released on PC.

After watching the gameplay video, it makes me wanna play GTA V right now.
